Comprehensive Automation Information Platform in Power Plant Based on Fieldbus Technology

The important significance of comprehensive automation information platform (CAIP) and the implementation by means of FCS are elaborated. Several solutions to implement CAIP in power plants in different condition are researched on and analyzed. The network architecture of CAIP based on fieldbus is proposed, functions and the roles of each part in the architecture are elaborated; two schemes for the implementation of the communication subsystem between management level, supervision level and field level, which is the key part in the implementation of CAIP in power plant, are proposed, merits and problems are pointed out for and the selection principle of the schemes is expounded. Operation practice with the proposed solution showed a good result and improved production efficiency in power plant. Significant economic benefit is achieved.
